What does the term "non-aeronautical" refer to in the context of airport land?

The term "non-aeronautical" in the context of airport land refers specifically to areas utilized for commercial activities that are not directly related to aviation. This can include various facilities and services that support travelers and the airport's operations but do not involve aircraft or flying. Examples might be retail spaces, hotels, restaurants, office buildings, and parking lots. These activities help generate revenue for the airport while not contributing to its core function of air transportation.

Understanding non-aeronautical land is essential for airport management because it represents an area of potential revenue that can be crucial for an airport's financial health. It allows airports to diversify their income streams beyond just passenger and cargo fees associated with aviation operations.
